According to one embodiment, in order to eliminate impurities, and the like, water to be treated is passed through each of reactor vessels, phosphorus contained in the water to be treated is removed by using an adsorbent, and thereafter the liquid held in each of the reactor vessels is discharged through each of first to third treated water discharge paths, thereby eliminating the impurities, and the like derived from the water to be treated. It is possible to eliminate the influence of the impurities in the water to be treated on the discharged desorption agent liquid containing phosphorus from the phosphorus adsorbent can be eliminated, and hence it is possible to obtain a phosphorus-containing liquid containing no substance other than the recovered phosphoric matter material.

According to one embodiment, water to be treated is passed through each of a first reactor vessel and second reactor vessel, phosphorus contained in the water is removed by using an adsorbent, thereafter the liquid held in each of the reactor vessels is discharged from each of a first treated water discharge path and second treated water discharge path, and thus the influence of soluble impurities derived from the water is eliminated. Further, when suspended solids impurities contained in the water are accumulated in the phosphorus adsorbent, the accumulated impurities are eliminated by a reverse cleaning operation using a liquid to be thereafter introduced from a reactor vessel liquid introduction path into the reactor vessel, and hence the influence of the suspended solids in the water on a desorption agent liquid to be thereafter introduced into a crystallization vessel, and containing phosphorus from the phosphorus adsorbent is eliminated.
